Would you avoid a party if you knew your ex was going?

Tom Cruise and Katie Holmes got their schmooze on at last night’s New York Times Golden Globes party at LA’s Chateau Marmont, but there was one guest they didn’t cozy up to — Katie’s ex-fiancé Chris Klein! Yes, while Tom and Katie made their rounds inside the party, Chris spent most of the night chatting up other guests outside on the balcony. Also worth noting: Katie’s longer hair! Between spending time with Chris and sporting a ‘do from her days on “Dawson’s Creek,” Katie had herself a little Flashback Friday! We wonder if Tom found it as amusing as we do.

Katie and Chris began dating in 2000 and became engaged three years later — but the romance fizzled out by 2005 and the couple remained friends, despite their split. They haven’t had very much interaction since then, though there was a crazy rumor floating around in 2006 that Chris was the biological father of Katie and Tom’s daughter, Suri. Something tells us Tom and Chris aren’t grabbing a beer together anytime soon.
